Primary Purpose: Treatment
||A Phase 3, Multicenter, Open Label Study to Assess the Safety and Efficacy of Nabi-HB Administered Subcutaneously in Patients With Hepatitis B Virus Associated Liver Disease Who Underwent Liver Transplantation
Primary Outcome Measures:
- To evaluate the efficacy of Nabi-HB administered subcutaneously weekly for a total of 14 weeks in patients who previously underwent a liver transplant. Levels will provide evidence if effective anti-HB levels >150 IU/ML can be maintained. [ Time Frame: 14 weeks ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To evaluate the safety of Nabi-HB administered subcutaneously weekly for a total of 14 weeks. [ Time Frame: 14 weeks ] [ Designated as safety issue: Yes ]

Experimental: Arm One: Nabi-HB
All subjects will be administered Nabi HB Subcutaneously
Biological: Hepatitis B immune globulin (Human)
Hepatitis b Immune Globulin (Human)(Nabi-HB) 312 IU/L per dose administered subcutaneously.
Dosage will be according to each patients body weight, as follow:
< 75 kg: 500 IU weekly ( may be increase to 1,000 IU weekly if anti-HBs levels are <150 IU/ML > 75 Kg: 1,000 IU weekly
- Hepatitis B Immune Globulin (Human)
This is a phase 3 prospective, single arm open label study to be conducted t approximately 4 study sited located in th e USA. Approximately 25 HBV DNA negative patients who underwent liver transplant at least one year prior, due to chronic hepatitis B infection will bwe eligible for study participation. The study consist of a total of 16 study visit and the duration of participation will be 20 weeks for each patients. Patients will be converted from the intravenous standard HBIG to Nabi-HB subcutaneous administration according to the individual scheduled dosing interval.
